"Which is best to take at night before I go to bed?"
Sensi chew "Insomnia" of course! It even has melatonin in each dose. The pieces are a strong 25 mg, so you may need to break them into smaller doses if you do not have much of a tolerance for edibles. Be careful about the taste as well.. I love tootsie rolls type candies and Sensi chews are absolutely delicious! Don’t eat too many like I did. I ate about half the bar and Slept for 14 hours.
